How was the "opt-in" done? Was it done with Mailman's confirmation
process, or would it have been possible for person A to accidently
or maliciously get person B on the list? If the latter, I would
consider the list mailing unacceptable.

A great deal of spam contains fake unsubscribe information. Indeed
following the "unsubscribe" information in spam often gets you "opted
in" to more lists because you have proved (1) that a human actually
reads the mail sent to that address, and (2) that the human who does
read that mail is gullible.

Obviously there are "too many" members of the list who do not believe
that they opted in to it. Why might that be?

You sound like someone defending "opt-out" mass mailing. I've
described above why people (correctly) avoid the opt-out instructions
in what the think might be spam.

This is normal practice to prevent the list managers from merely
engaging in "list washing" (removing the complainers while continuing
to send the spam to many people who never really wanted it but don't
bother to complain.

That is a good idea. This is really the only way your customer can
continue with the mass mailing. There may have been things that your
customer might have done earlier to prevent this state of affairs,
but at this point, what the hosting providers are suggesting is the
only way forward, unless your customer can document how each address
came to be added to the list with some evidence that the person who
reads mail at that addresses confirmed the process.

I certainly have experience from the other end. A few years ago some
unknown person signed me up to scores of lists that didn't do proper
confirmation. Apparently, this bit of abuse is known as "list bombing".

Your customer will either have to
(1) do what the hosting company says (and that can be done with
mailman) or
(2) prove that each address was added by the person behind that
address or
(3) close up shop or
(4) find a spammer friendly hosting service.
